Chapter 5 — Commercial & Contractual Bonds
Surety Bonds in Private Construction Projects
Private construction contracts may also require bonds — bid, performance, advance payment, payment, warranty or maintenance forms among them — where the contract provides for the requirement and the applicable Surety is prepared to issue.
Direct answer
Bonds are not exclusive to public works. A private owner and a contractor may agree on security requirements at tender, during construction, in connection with an advance payment, for payment obligations, or after completion. The requirement comes from the private contract, not from public procurement rules.
Private contract terms govern
Public procurement rules and bidding documents do not apply to a private construction contract unless they genuinely apply to the arrangement. Private owners sometimes adapt procurement language or forms, but the requirement is still contractual: what counts is what the contract says.
That has practical consequences. Permitted forms, amounts, validity periods, release mechanisms and prescribed wording in private work are negotiated, so they vary from project to project.
Bonds that may appear in private construction
- At tender stage — where the owner runs a competitive process and requires security for the bidder''s commitment.
- Performance — see How Does a Performance Bond Support a Construction Contract? and What Is a Performance Bond?.
- Advance payment — see What Is an Advance Payment Bond?.
- Payment obligations — see What Is a Payment Bond?.
- After completion — see What Is a Warranty / Maintenance Bond?.

Important considerations
- No private project requires all of these bonds, and many require none.
- One bond does not automatically become another. A tender-stage bond does not convert into a performance bond on award.
- A bond supports the obligation described in it. It does not guarantee project success or quality, and it does not pay automatically on demand.
- Whether a requested form can be issued depends on the obligation, the wording, the circumstances and the applicable insurer or Surety requirements.
Practical points for contractors
- Read the security provisions of the private contract in full, including any annexed bond form.
- Confirm the named Principal and Obligee, the amount or basis, the validity requirement and prescribed wording.
- Check how variations, extensions and milestone payments affect the security required.
- Allow time for evaluation by the applicable insurer before contractual deadlines.
Key considerations
Evaluation, underwriting, requirements, terms, approval and issuance remain functions of the applicable insurer or Surety. SuretyPH provides information, accepts inquiries, helps organise supporting documents and communicates status; it does not determine whether a contract legally requires a bond, whether an obligation is bondable, the bond wording, the premium, collateral, underwriting approval, contractual liability or claim entitlement.
Key takeaway
Private construction bonds come from the private contract, not from procurement rules. Read the contract's own security provisions, and do not assume a public-works requirement applies.
